Research on the inhibitory characteristics of new polymer dust suppressants on lithological particles

Abstract

To reduce the pollution of the roadway environment and the damage caused by the personnel and equipment by the dust escaping from the fully mechanized driving face, a chemical and environmentally friendly dust suppressant with strong wettability and strong adhesion was developed based on the engineering background of the west-wing track roadway of Jining Jinqiao coal mine, and inhalable dust as the research object, with surfactants as the key skeleton and inorganic salts and polymer adhesives as auxiliary materials.The results of field verification show that the chemical dust suppressant has a better ability to lithological particles and can effectively reduce the concentration of respirable dust in the roadway.
